I was hesitant to buy this will all the size complaints that have been posted. My frame was for a 10+ year old 10x20' Costco shelter and I really expected that I'd need to shorten some pipes. I rolled it out on the roof and was thinking it wouldn't work, but took my time working around the tent in circles, stretching and tightening it down. It's really tight and hard to do, but once it's attached it fit the frame like a glove...better than OJ. I can only guess that others were trying it on a Shelter-logic frame, but I am also super handy and patient with repairs. My only complaint is the colour, it would have been nice to have a tan option. It's really a 10 start product, but I'm not sure the material will last as long...only time will tell.
